New flange or flange extender

01-03-2009, 12:33 PM

I am installing a new tile floor. The current flange sits directly on the concrete. After the tile is installed, the flange will be a 1/4 inch below the tile. What is the best solution, a new flange, extender, bigger wax ring? What is the proper way of doing this if it was a brand new house? Is it hard to remove a flange from a concrete slab?

There is no way I would use a flange extender or double wax ring. I would cut out the old flange if it's pvc or break it out if it's c.i. Put a spacer around the riser and tile right up to it. Then set your collar. The collar must sit on the floor.

I've never had a problem with the Sioux Chief raise a rings, but I usually pull the flange screws, clean the old flange well, silicone the raise a ring down, and then reinstall longer and fatter flange screws. Add that to a standard wax ring with a horn, and I've not had any trouble.

okay, so no horned ring? I hear two things depending on who I ask. Is there a reason not to use the horn?

Also, what is the advantage of doubled rings over say an extra thick ring?

It's a personal preference regarding the horned wax ring. I despise them, and would only use one if I had to on a lead bend. If you're going to double wax it, and one of those waxes is horned, you're asking for trouble. I don't like horned wax rings, because it has a reduced size on the one end.
